configure.in calls AC_PROG_OBJC and libSDL_image_la_SOURCES carries an
Objective-C source, so automake selects Objective-C as the link language
for the library and emits:
libSDL_image_la_LINK = $(LIBTOOL) ... --mode=link $(OBJCLD) \
$(AM_OBJCFLAGS) $(OBJCFLAGS) ...
OBJCLD = $(OBJC)
AC_PROG_OBJC detects a bare compiler carrying none of TOOLCHAIN_OPTIONS,
so while compilation goes through $(CC) and is fine, the link drops
--sysroot and the tune flags and falls over:
ld.lld: error: cannot open crtbeginS.o: No such file or directory
ld.lld: error: unable to find library -lpng
ld.lld: error: unable to find library -ljpeg
ld.lld: error: unable to find library -ltiff
ld.lld: error: unable to find library -lz
ld.lld: error: unable to find library -lSDL
Export OBJC as CC so the link gets the full toolchain options.
configure.in already forces OBJCFLAGS=$CFLAGS, so that needs nothing.
